Comment 2 Mike Gahagan 2016-08-22 15:41:17 UTC

The dmidecode released with 7.2 had partial SMBIOS 3 support, I think some of the needed kernel bits were missing for SMBIOS 3 to be fully supported on all platforms. RHEL 7.3 contains an updated dmidecode and necessary kernel updates for full SMBIOS 3 support. Please try one of the recent 7.3 releases, anything more recent than mid-July should be sufficient. All you should need is the updated dmidecode and possibly the kernel. 

The latest dmidecode package for 7.3 is 3.0-2.el7. If you are seeing issues with that dmidecode package, please let us know what hardware you are seeing it on.

I will check version 3.0-2.el7.

thanks.

Comment 4 Mick Brennan 2016-08-26 11:15:41 UTC

dmeidecode-3.0-2.el7 does fix this. it supports SMBIOS 3.0

Do you know if this will be fixed in RH 6.8?

Comment 5 Mike Gahagan 2016-08-26 19:50:15 UTC

dmidecode-2.12-7.el6 is the package currently in 6.8. It has some support for SMBIOS 3 similar to the version in RHEL 7.2. RHEL 6 is getting close to entering maintainence mode so feature requests are very limited. If IBM needs dmidecode 3.0 in 6.9 the feature request should be opened ASAP.
